[0002] An optical fiber is a light guiding fiber used for transmitting optical signals, and is widely used in multiple fields such as communication, network, medical treatment, and sensing. It is mainly made of transparent glass or plastic materials, and uses the principle of total internal reflection to transmit optical signals. With its advantages such as high bandwidth, low loss, and anti-electromagnetic interference, the optical fiber has become an indispensable part of modern communication systems. There are various optical fiber accessories, and according to different usage situations, there are corresponding assembly accessories. For example, for optical fiber plugs, common plug types include LC, SC, ST, MPO, etc., which are suitable for different usage occasions; for the assembly connection of optical fibers and plugs, currently, most are assembled manually. For example, for the optical fiber cold splice for SC interface, the existing operation method is to gradually install each accessory on the optical fiber, resulting in low assembly efficiency. Based on this, the present invention proposes an assembly machine that operates on the optical fiber cold splice for SC interface, which can omit the relatively cumbersome manual assembly steps and improve the assembly efficiency of the components.

An arc-shaped groove 101 is formed on the base 1, and the position cylinder 18 moves on the arc-shaped groove 101.

[0027] Working principle: The optical fiber cold splice of the SC interface generally consists of a sheath 2, an interface body 3, and a tail sleeve 4. The sheath 2 is sleeved on the interface body 3, and the tail sleeve 4 is sleeved on the end of the interface body 3. There is a threaded connection between the tail sleeve 4 and the interface body 3. A threaded portion is provided at the end of the interface body 3, and the threaded portion is formed by rotational docking; during assembly, each fitting is installed in sequence, that is, the sheath 2 is installed on the first clamping seat 8, and the first clamping cylinder 14 is used to control the first clamping seat 8 to clamp and install it; the interface body 3 is installed on the second clamping seat 9, and the second clamping cylinder 15 is used to control the second clamping seat 9 to clamp and install it. There is a gap reserved between the sheath 2 and the interface body 3; further, the tail sleeve 4 is installed inside the positioning cylinder 22. By controlling the first motor 27 to work and the first gear 28 to rotate, the control ring 23 is rotated. The pushing portion 26 is pushed by the contact portion 29, so that the clamping plate 24 moves and clamps the tail sleeve 4 for installation. There is a gap reserved between the tail sleeve 4 and the end of the interface body 3.

[0028] After completing the assembly of the fittings, the operator processes the end of the optical fiber, that is, cuts the optical fiber and wipes and cleans the inner core of the optical fiber with alcohol. First, the deflection motor 16 is used to control the deflection of the deflection frame 17, and the position cylinder 18 is used to control the movement of the extension cylinder 19, so that the extension cylinder 19 is located at one end of the threaded portion on the interface body 3. Then, the telescopic rod of the extension cylinder 19 extends to the inside of the threaded portion, and the deflection frame 17 is controlled to reset and deflect, so that the docking thread 21 can be lifted and deflected; further, the optical fiber is passed through the tail sleeve 4 and the interface body 3 in sequence, so that the optical fiber is installed on the interface body 3; the extension cylinder 19 is controlled to deflect to the outside of the docking thread 21, and by controlling the deflection of the extension cylinder 19, the docking thread 21 is pushed back to its original position, that is, the docking thread 21 is docked with the fixed thread 20. After the optical fiber extends into the interface body 3, the docking thread 21 resets and deflects to its original position to press and limit the optical fiber.

[0029] Finally, by the operation of the first motor 6, the first lead screw 7 rotates to drive the first sliding seat 10 and the connecting seat 30 to move. The tail sleeve 4 is sleeved outside the fixed thread 20 and the docking thread 21. By controlling the operation of the second motor 31 and the rotation of the second gear 32, the positioning cylinder 22 is rotated, and then the tail sleeve 4 is threadedly connected to the threaded portion; further, by the operation of the second motor 11, the second lead screw 12 rotates and the second sliding seat 13 moves to transfer and install the sheath 2. The sheath 2 is sleeved outside the interface body 3 to complete the assembly of the fittings; in this embodiment, after positioning and installing each fitting of the optical fiber cold splice of the SC interface, the operator only needs to pass the optical fiber through each fitting, and the subsequent assembly of each fitting can be realized by automatic docking assembly, eliminating the manual docking assembly operation, thereby improving the assembly efficiency.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
